Find the pillow inserts at any RV store or Walmart. They have material on one side and silver reflective material on the other side. That slip right into the roof vent opening. Do not buy the rubber ones.
There is one probably more important thing to do to your vents for a combination of reasons:
Install, or have installed, external vent covers up on the roof over the vent lids. These external covers 1) Stop the sun's UV rays from rapidly destroying the plastic vent lids, 2) Allow the vent lids to be open when it's raining and/or windy so as to still maintain good internal ventilation, and 3) Reduce heat into the interior from the vents by creating an insulating layer of air between the vent lids and the vent covers.
It's a win all the way around to have external vent covers installed. Here's an example of what I'm referring to (you install them with the grilled opening facing to the rear of the RV so air doesn't get rammed into them when traveling):
